John Blund (or Johannes Blund, Iohannes Blondus, Iohannes Blundus; circa 1175–1248) was an English scholastic philosopher, known for his work on the nature of the soul, the Tractatus de anima, one of the first works of western philosophy to make use of the recently translated De Anima by Aristotle and especially the Arab philosopher Avicenna's work on the soul, also called De Anima.[1] He taught at Oxford University[2] along with Edmund of Abingdon. David Knowles said that he was "noteworthy for his knowledge of Avicenna and his rejection of the hylomorphism of Avicebron and the plurality of forms.",[3] although the problem of the plurality of forms as understood by later scholastics was not formulated explicitly in Blund's time.[4]Maurice Powicke calls him the "first English Aristotelian."[5]
